Social cohesion

Tongnan Dafosi Wetland Park is located on both sides of Fu River flowing through the central area of Chongqing Tongnan District. Its south side is right next to the national tourist spot – the Great Buddha Temple (Dafosi). Due to the increasing frequency and severity of extreme rainstorms, the area is prone to floods. To build an urban wetland park that is adaptive to floods, designers retained the original wetland environment along the river channel and set up pedestrian corridors to enable citizens’ close contact with wetland nature. [1, 3] This project excavates two important cultural elements of Tongnan: 1) the shipping culture with a long history; and 2) the Buddhist culture based on the Great Buddha Temple. [1]

The Gangxia 1980 green roof, a pilot of the Green Cloud project, was launched by The Nature Conservancy (TNC) in collaboration with key partners, including: Zhubo-AAO; Glocal Estate Management; and Urban Planning & Design Institute of Shenzhen (UPDIS) [1]. Located on an old building in Gangxia village in Shenzhen, the project utilizes three-dimensional light steel structures that are simple to construct and have the capacity to hold over 420 plant containers, filled with plants mostly native to Southern China [1, 2]. The original concrete rooftop is transformed by vegetation, which is capable of absorbing and preserving rainwater, creating a nature-based stormwater management system for the residential building, achieving a 65% of run-off control rate [1, 2]. As a result, a living “green cloud” is formed on a rooftop of Gangxia village, showcasing “a model to improve the urban village’s stormwater management system and its living environment” [1. p.33].

In 2014, a rooftop farming project was initiated in the informal settlements of the Greater Cairo Region to address challenges brought by climate change and to empower the local community. The project was initiated by the German Corporation for International Cooperation and a local NGO with the objective to "reduce ambient temperatures (microclimate) in a densely populated area through green spaces on rooftops, and reduce the impacts of the urban heat island effect and increasing heat." (1) The initiative also addressed four of the Aichi Biodiversity Targets by tackling biodiversity loss, encouraging sustainable agriculture practices, fostering ecosystem services and developing local knowledge (1,11)
Besides environmental benefits, the project and its scaled-up project in 2017 brought several socio-economic benefits by reducing vulnerability to food price changes and by developing the local community. Rooftop Farming Hubs were also established to foster the training and knowledge sharing of rooftop farmers in Cairo (1).

The redevelopment of the Bishan-Ang Mo Kio Park (Singapore) saw the naturalisation of the previously channelised Kallang River, as well as the installation of wetland cells as water cleansing biotopes and creation of butterfly habitats (Ref. 1).

The Kallang River was previously confined to a concrete canal that ran to the southern edges of Bishan-Ang Mo Kio Park (Ref. 1). The channel segregated the two residential areas situated on either side of the park, with the river's 2.7km continuous concrete channel being crossable at only certain defined points (Ref. 3). Following its naturalisation, culminating in 2012, the now 3.2km meandering river is considered the park's highlight, "merg[ing] seamlessly with the park's greenery" (Refs. 1 & 6), and creating a "blue-green recreational network which is well-integrated with nearby residential areas" (Ref. 2).

Two River Urban Park is a public space located towards the confluence of the Liesbeek and Black Rivers and is one of the largest urban green lungs in the City of Cape Town. It is approximately 240 hectares in extent. The Park comprises sensitive ecological systems and habitats, extensive open space areas, institutions, historical buildings and cultural landscapes (2). The City of Cape Town and the Western Cape Province own significant proportions of the park and in 2011, the Western Cape Government started considering the sustainable redevelopment of the TRU Park into a mixed-used urban green area including housing development, heritage protection, the rehabilitation of the degraded environment and recreation opportunity creation (1). Since 2016, the project has been on hold due to the modification of the planning law Local Spatial Development Framework that affects the redevelopment plans of the Two Rivers Urban Park (1).

"Cape Town Environmental Education Trust (CTEET) is a non-profit environmental education organization that seeks to improve both the inclusiveness of urban nature reserves and the effectiveness of biodiversity conservation by connecting nearby disadvantaged and racialized communities with municipally-owned nature reserves." (1 p15) CTEET has 3 flagship projects: providing low-cost environmental education programs to children, offering training and development to Cape Town youth to access jobs in the Green Economy and supporting and driving conservation initiatives in Cape Town through its Nature Care Fund (2).

"The Urban forest strategy (UFS) is a central part of an innovative overarching policy framework of the City of Melbourne underpinning the city's aim to create healthy ecosystems for people and nature" in the period between 2012-2040 (1 p9). The UFS outlines a scientifically-vetted long-term process to re-nature the city with a diverse selection of urban trees and open space for and with the citizens, combining elements of an eco-managerial governance arrangement with an open and reflexive co-governance approach. (1 p11). The Strategy concentrates on 6 areas to achieve its goals: canopy cover, forest diversity, vegetation health, water quality and soil moisture, urban ecology and environmental stewardship among citizens.

The Barr Foundation started the cross-cutting program called Waterfront Initiative to support the sustainable planning and accessibility of the waterfront area while also increasing residents awareness and environmental stewardship of the waterfront. The Waterfront Initiative initially supported organizations in harbour planning, designing waterfront parks, and climate resilience efforts along the Boston waterfront. In 2018, it has also strengthened its focus on social equity and public engagement across more vulnerable neighbourhoods around waterfront issues (1,2)

"In Winnipeg, there are several downtown neighbourhood groups (such as the Spence Neighborhood Association, and the West Broadway Community Organization) that make use of vacant urban space for the benefit of indigenous communities, and encourage them to maintain green spaces, ‘tot lots’, and a network of dozens of community gardens. There are also community-led indigenous ‘healing lodges’, Indigenous gardens, medicine gardens, as well as a land-based education programs (e.g. Marymound) using gardening to help at-risk indigenous youth heal from trauma and build resilience in these neighbourhoods." (1 p41).
One such community gardens are the Chief Grizzly Bear’s Garden (in its official, Anishinaabe name: Ogimaa Gichi Makwa Gitigaan) focusing on increasing the visibility of the indigenous community in the Spence Neighbourhood and providing public space for gathering and traditional indigenous ceremonies honoring their connection to nature. The garden is also the place for cultivating native plants significant for traditional medicine practices (1).

Another NBS initiative supporting the indigenous community in Winnipeg will be the Clan Mothers Healing Village and Knowledge Centre (CMVH) initiated by The Elders of Winnipeg. The CMVH will be located in rural Manitoba and provide a land-based, nurturing community living environment for indigenous women and youth who have been victims of intergenerational trauma, sexual/domestic violence, or human trafficking and support their reintegration into society.

Winnipeg lies at the confluence of the Assiniboine and the Red River, a location known as 'The Forks', which is the cultural centre and meeting place of the city. "The winter use of the river went through an unprecedented change over the last 10 years, organized by a private company (The Forks North Portage Partnership), that began to operate the 'Red River Mutual Trail', the longest Guinness World Record-holding natural skating trails on the Red and Assiniboine rivers, offering opportunities for skating, curling, cycling, walking, and cross-country skiing, along with cultural events and unique, community-designed warming huts, a restaurant on ice, art exhibitions and other activities. The river trails also links otherwise distant neighborhoods, and functions as a transportation and commuting route with a variety of access and exit points during the city’s typically 4-5 months of winter climate."
